Polarography molecular conformation

Some of the properties of phenoselenazines, including polarography, electric resistivity, ESR, NMR, crystal structure, and molecular conformation, nuclear spin coupling constants, the cation radical equilibrium constant and the heat of dimerization, the ESR spectrum and mechanism of photoreduction, and the semiconduction behavior of phenoselenazine-iodine complexes, have been reported.

The segments of dh DNA with distorted conformation desorb from the mercury electrode at the potentials by c. 0.2-0.3 V more negative than are the potentials of the peak 1 [102]. This desorption results in an appearance of the peak 2 on a.c. polarograms, which can be detected only for carefully isolated high-molecular mass nucleic acids and with the aid of in-phase component of phase-sensitive a.c. polarography. Peak 2 occurs at still more positive potentials than the peak 3 yielded by the corresponding ss nucleic acids [102].
